It is found that HelI 4686 ,is emitted in ithe same cold region of < 10000 K as hydrogen, metal and neutral helium emission lines. This conclusion is based on the finding that the observed width of 24686 is the same as the calculated width of 24686. The calculated width is derived from the observed

โฆ Synopsis
The excitation of the levels 21P, 31D, 51D, 61D and 71D of helium in quiescent prominences and the chromosphere is considered using the observations made during the
